Yep, the windows version is terrible, get the Desktop App it's far more stable.
i've had the worst luck with gi support, i've been waiting 6+ months to fix my premium pass buy and alliance flight issueDepends on what you mean by "keeps crashing and freezing". If it is every few minutes, then contact G! support through the official website.
If it is a few times per day, this is "normal" for the Windows version.
A few tips for Windows users:
- If you collect a bunch of fuel from your gifts and send off planes --> visit Madlen before collecting pax from your own city
- if you get a very important drop from a collection --> go visit Madlen
- If you are running a VC contract --> visit Madlen every ~12 buildings that you bring into your Magic Square/Garden
Basically... any time something significant happens, go visit Madlen to 'save' your progress. Even if the game crashes when I visit her, the progress is saved for me.
If you hate this option, then look into how to transfer your game to one of the other options (I am definitely NOT the expert on this!)
Happy flying!
